A radiographic camera has a housing, having first and second ends, that encloses a conduit having a radiographic source. The conduit is in communication with a lock assembly at the back end of the camera and to a connector assembly at the front end of the camera. The radiographic camera c an be held within a jacket that has a handle with a reinforcement structure. Th e conduit is surrounded by a radiation shield that has a shield end attached t o an endplate having a port outlet. The connector assembly features a front plate having a hole aligned with the port outlet on the endplate. The front plate features an internal surface to which a rotor is rotatably attached. T he rotor provides a first rotor hole that is aligned with the port outlet and includes a port shield for blocking the first rotor hole, and a second rotor hole that is alignable with the port outlet. The rotor may be rotated so tha t either the first or second rotor is aligned with the port outlet to shield o r expose the source.
